Further investigation found that towns are not held to the same WI state statutes as villages and cities.
Also to the question by Danah Zoulek as to whether or not Rock Brandner had a conflict of interest when voting. Here is the response from the Wisconsin Election Commission to a question in that regard.
"As you noted, Wis. Stat. 8.11(1m) only applies to villages, not towns. The default under that statute is that there will not be a primary election for village offices, but the village board may vote to hold a primary. There is nothing in the election laws which establishes a conflict of interest if a trustee votes to hold a primary. The conflict of interest provisions in the Ethics Code are under the jurisdiction of the Ethics Commission, so you may contact that office to confirm, but typically those rules prohibit financial self-dealing by elected officials, so I would be surprised if such a vote implicated those statutes."
